Abstract

A method and apparatus for communicating over a network is provided. The method includes selecting between location-sensing methods for an LBA, such as between GPS and network triangulation. For each location-sensing method, a dynamic determination is made as to whether the accuracy of the location-sensing method, in the current environment, meets the application requirements. If two or more location-sensing methods meet the application requirements, then, location-sensing method selected is the location-sensing method that, from among the location-sensing methods that meet the application requirement, consumes the least power. Otherwise, the location-sensing method that is most accurate for the current environment is selected.
